A driving device for a passive closed variable topology packaging robot mechanism

Abstract

The invention discloses a driving device for a passively closed type packaging robot mechanism capable of changing topology. A rotating disc capable of rotating around a central shaft is installed on the central shaft of the driving device, first telescopic rod assemblies are composed of third connecting rods, first thick telescopic rods, first thin telescopic rods and first sliding blocks, one ends of the first thick telescopic rods are welded to the third connecting rods, the other ends of the first thick telescopic rods are connected with the first thin telescopic rods through cylindrical pairs, the bottom parts of the first thin telescopic rods are connected with the first sliding blocks through ball pairs, the third connecting rods are connected with sliding rods through ball pairs, the first sliding blocks are arranged in sliding chutes in triangular metamorphic rods, and the first sliding blocks can move along the sliding chutes. The driving device is simple in structure, flexible in driving, convenient to control and free of interference with other rod pieces in the motion process, and the opening and closing of the top of the packaging robot mechanism capable of changing the topology can be skillfully completed.

Description

Technical field [0001] The invention relates to the field of mechanical design, in particular to a driving device of a passive closed variable topology packaging robot mechanism. Background technique [0002] In recent years, with the continuous development of society, robots have gradually entered all walks of life, and the production of products is often inseparable from packaging. Therefore, packaging robots have gradually become a hot spot of research. Chinese patent ZL201210218278.7 has published a Variable topology packaging robot mechanism, the packaging robot mechanism can change topology, complete packaging tasks at one time, simple structure, stable and reliable molding, greatly reducing the procedures of multi-station, multi-module packaging machinery, and improving packaging efficiency while satisfying people There is a changeable demand for food packaging, but the packaging robot mechanism has not yet designed a top closure drive device, which makes the top of the me...

Problems solved by technology

[0002] In recent years, with the continuous development of society, robots have gradually entered all walks of life, and the production of products is often inseparable from packaging. Therefore, packaging robots have gradually become a hot research topic. Chinese patent ZL201210218278.7 announced a Variable topology packaging robot mechanism, the packaging robot mechanism can change the topology and complete the packaging task at one time. There is a demand for changing food packaging forms, but the packaging robot mechanism has not yet designed a top closing drive device, which makes the top of the mechanism unable to close. Therefore, it is necessary to design a top that is simple in structure, flexible in control and does not interfere with the mechanism itself Open and close drive

[0003] At present, there is no innovative invention design of a top opening and closing drive device with simple structure, flexible control, passive closure, easy maintenance and suitable for the packaging robot mechanism.
